Senior Low-level Control Engineer - End-Effectors

About the Role

We are looking for a Senior Low-level Control Engineer to join our Control Team in London, focusing on control development and integration for our end-effectors.

You will design, implement and validate actuator- and joint-level controllers and grasp-level behaviours across a family of end-effector variants - parallel and multi-finger grippers, vacuum and suction tooling, and purpose-built tooling for specific customer tasks. Each variant brings different actuation, different sensing and, critically, different transmission mechanisms: geared direct drives, cable- and tendon-driven routings, differential and coupled linkages, and underactuated designs where few actuators must produce adaptive, compliant grasping across many degrees of freedom.

The ideal candidate has a solid background in control theory, strong software engineering skills in C++, and comfort working from real-time embedded control up through kinematics/dynamics and hardware debugging. You will work closely with mechanical and hardware engineers - early enough in the design cycle that your input shapes actuation and transmission choices rather than merely inheriting them.

Cross-Disciplinary Collaboration

• Close the loop with mechanical/electronics engineers across sites on actuation, transmission and sensing requirements.

• Work with data collection, applications and deployment teams so end-effectors work reliably in real use.

What We're Looking For

• Shipped real-time-safe, object-oriented C++ control software running on real hardware.

• Tuned and validated controllers on physical actuators, including sensor calibration and bring-up.

• Modelled, identified and controlled through real mechanical transmissions - gearing, cables/tendons, differentials, coupled linkages or underactuated mechanisms - and dealt with the compliance, friction and backlash they introduce.

• Worked on end-effectors or comparable multi-DoF mechanisms, including grasp control and supporting sensing.

• Debugged at the fieldbus and OS layer: e.g. EtherCAT or CAN, on an RTOS or real-time Linux.

• Strong control theory foundation (linear/nonlinear control, stability, observers, state estimation, feedback/feedforward, filtering, frequency-domain analysis) applied to multi-DoF mechanisms via Jacobians, numerical IK/FK, and URDF/Xacro.

Nice to have:

• BLDC motor control (commutation, current control, torque optimization).

• ros2_control internals (hardware interfaces, controllers, controller_manager, plugins, lifecycle nodes).

• Tendon- or cable-driven mechanisms specifically, including pretension management, routing friction and wear behaviour.

• Tactile sensing integration; vacuum and suction tooling, including multi-cup arrays and grip-loss handling.

• System identification toolchains and simulation environments (MATLAB/Simulink, MuJoCo, Isaac Sim).

What We Offer

• Competitive equity: stock options with meaningful upside as we scale.

• 30+ paid days off, including 23 days of annual leave, all UK bank holidays, and additional company closure days (including Christmas–New Year shutdown).

• Private healthcare, including virtual and in-person care.

• Pension scheme with 8% total contribution (5% employee, 3% employer) on full earnings.

• Free daily breakfast, catered lunch, and snacks in-office.

• Work at the frontier - collaborate daily with world-class engineers, researchers, and product experts building the next generation of AI and humanoid robotics.

• Real ownership - direct access to founding leadership, meaningful input on product direction, and the ability to drive key initiatives from day one.
